I would encourage you to try SNA. While the facilities VX has at Terminal 3 are nice, it is still the old, dowdy T3. Blah by anyone's standards.
When you get on the plane and open your device it will find the WiFi signal. To speed your efforts along, it's nice to already have an account with GoGo and not have to set all that up from your plane seat. With an account pre-built, you just log in and start using it. Visit
